This invention-relates to certain improvements in building blocks and itis an object i, v of the invention to provide a novel and im provedblock of this general character which a afiords effective protectionagainst frost and dampnessand also constructedin a manner wherebyplaster may be applied directly to the inside surface thereof withoutthe use i of lathing.

It is also an object of the invention to pro vide a novel and improveddevice of this general character comprising spaced slabs whereby apartition wall may be assembled with respect to an outside wall;

efiectively. connected and held in desired assembled relation, saidconnecting means providmg hand grasps whereby the block may be readilymanipulated by the workman and whereby the blocks may be laid withprecision.

An additional vobject ofthe'invention is '20 to provide a block of thisgeneral character comprising spaced slabs made from a wet mix togetherwith'tiesconnecting said slabs andmaintaming the. same in desiredassembled relation, said ties constituting clay L bricks whereby thecompleted block possesses a maximum of strength,

The invention also has provide a novel and im prising spaced slabs'anfor an object to roved block comwherein the edge walls of said slabshavedisposed therealong bond grooves whereby the holdin mortar or thelike edectively holds the bloc against slippage and which grooves alsopermit the effective placing or mounting of aground s5 between adjacentblocks.

The invention consists in the details of construction and in thecombination and an rangement of the several parts of myimproved buildingblock whereby certain imcc portant advantages are attained and thedevice rendered simpler, less expensive and otherwlse more convenientand advantagoons for use, as will be hereinafter more Iully set forth. I

The novel features of my invention will hereinafterbe definitelyclaimed.

In order that m invention may he the will'now proceed to describe thesame with reference to the accomwherein Figure 1 is a-view inperspective of a block constructed in accordance with an embodiment ofmy invention;

itudinal sectional view look as illustrated in 1 wit the tie members intop plan;

Figure 2 is a 1011 Figure vention and wherein the blocks are adapted 65for use in connection with a floor joist; F1 re 6 is a view in top planillustrating stlll another embodiment of my invention Figure 7 is a Viewin top plan illustrating a still further embodiment of my invention foruse at a corner;

Figur 8 is a view partly in plan and partly in section illustrating howa window frame may be assembled in connection with my improved block;

Figure 9 is a fragmenta elevational view of a wall constructed of b ocksmade in accordance with an embodiment of'rny inven- 30 tion and showinghow a roof plate may be held to the wall; Figure 10 is a view inperspective of the wood ground.

As particularly illustrated in Figures 1, 2 3% and 3 of the drawings, myimproved block comprises a pair of spaced slabs 1 preferably formed of adry mixed concrete. said slabs being connected by the ties 2. Each ofthe ties 2 preferably comprise a common clay en brick as generallyemployed. An end portion of said tie partially extends within one of theslabs 1 while the opposite end portion extends entirely through thesecond slab with its end face substantially flush with the 95 outer faceof such slab.

The tie members or bricks 2 provide effective 'ips whereby the block inits entirety may e readily manipulated by a workman and whereby a blockmay be set in a wall ice with utmost precision. The tie members 2 arepreferably positioned at the transverse centers of the slabs 1 and adecided distance inwardly of the ends thereof. These tiemembers 2 which,as hereinbefore stated, are 105 common cla bricks readily absorbmoisture which may e between the slabs resulting in a wall that is bothdamp and frost proof and. whichcondition is further facilitated in viewof the fact that an end of a tie 2 ex no tends entirely through one ofthe slabs whereby the drying efiiciency or character istic ofthe tie ismateriall increased. Furthermore, the tie 2 draws t e moisture out ofthe slabs and holds it until it can pass out through the hollow walls.This feature is of especial value and importance as in actual practicethere has been clearly established the fact that the tie overcomes thedisadvantage of dampness and sweating collecting on the inside wall.

The inner or exposed end of the tie 2 also provides a bonding area forthe plaster applied to the wall as such plaster will adhere etger to thetie 2 than to the surface of the s.a

The edge walls or faces of each of the slabs 1 have disposed entirelytherealong the bond grooves 3 which, when filled with mortar between twocourses, renders sli ping almost impossible. From the stan point of theworkman, these grooves make it much easier to lay the blocks as thegrooves form an opening which allowthe blocks to '4 of wood, said platebeing provided-in opsettle down exactly to line and the groovesproviding a space for surplus mortar. These grooves 3 also permit theeffective insertion etweenadjacent blocks of a ground plate posedsurfaces with the outstanding ribs 5 which snugly engage within theadjacent grooves 3. These grounds are adapted to be positioned within awall as the occasions of practice may require to permit the propermounting of picture molding and the like. The s abs 1 are spaced apart adistance to provide a relatively thick wall whereby liability ofoverturning is prevented and by employing bricks as the tie members amaximum of strengthin, assured as such bricks will be considerablystronger than the use of concrete ties.

In Figure 5 I illustrate a air of blocks adapted to 'provide for the eective mount ing of a floor joist and wherein it is to be noted that anend of an inner slab 1' terminates a slight distance inwardly of theouter slab providing a space which will readily receive an end ortlon ofa joist A and permitting said joist to extend within the space betweenthe-slabs.

As illustrated in Figure 6, the inner slabs 1" also terminate inwardlyof the outer slabs to provide a second space and wherein the blocks of apartition wall may be readily interlocked with the outer wall.

In Fi re 3 I illustrate a further embodiment 0 -m invention wherein theblock is relatively s ort as may be required and having only a singletie member or brick 2 connecting the central portion of the slabs 1.

r In Figure 7 I illustrate an embodiment of m invention wherein theblock is constructfor use at the cornerof a wall and where- I in theouter slab 1' is extended as at 6, 8.

vide-d with an outstanding flan 10, said, flange 10 providing a readyhan grasp for the worker in carrying or setting t e block;

, In Figure 8 I illustrate the ease with which? a window frame may beconstructed in con nection with my improved block and as the same isbelieved to be obvious from such Figure 8 a detailed descriptionrelative thereto is unnecessary.

It is to be noted that the outer face of one of the slabs of my improvedblock may be roughened as by small stones or ebbles to ive a finish tothe block and it is also beieved to be readily understood that informing the slab of a dr mix, plaster may be readily applied to t einner surface of a wall without requiring the use of laths as is nowgenerally done.

From the foregoing descri tion it is thought to be obvious that abudding block constructed in accordance with my invention isparticularly well adapted for use by reason of the convenience andfacility with which it may be assembled and operated, and it will alsobe obvious that m invention is susceptible of some change anmodification without departin from the principles and spirit thereof anfor this reason I do not wish to be understood as limiting myself to theprecise arrangement and formation of the several parts herein shown incarrying out my invention in inafter claimed.

I claim:- 1. A building block comprising a pair of spaced concreteslabs, and a clay brick con-' nectin said slabs and constituting amoissture absorbin element, one end portion of; the brick partiallyextending within one of the slabs while the opposite end portion off thebrick extends entirely through a second slab with its end facesubstantially flush with the outer face of said second slab.

2. A building block comprising a pair of spaced concrete slabs, and atie member con-' necting said slabs, said tie member being an absorbentof moisture, one end portion of the time member partially extendingWithin one of the slabs while the op osite end portion of the tie memberexten s entirely through a second slab with its end face subpracticeexcept as hereb stantially flush with the outer face of said GEORGE w.MoDEARMON. v
